HYDROCARBON MOTOR.

Application filed .Tune 11, 1920. Serial No. 388,129.

7;0 all wlwm 'it may Concern:

Be it known that I, LIONEL M. WOOLsoN,

a citizen of the United States, and resident of Detroit, IVayne County, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon' Motors, 'of which the following is a specification.

This invention relates to hydrocarbon motors, and particularly. to means for heating the mixture passing from the carburetor to the motor cylinders.

The application is in part a division of my pending application Serial No. 323,627, filed September 13, 1919, and in part a conl tinuation of my Patent No. 1,448,651, dated March 13, 1923.

The invention relates more specifically to the combustion device' which 1s less fully illustrated in said vpending applications, and

it comprises a body having inlet and Outlet Vopenings and having meansl forA receiving a s ark plug and an observation window. At tiie inlet Opening thereis a means for holdi a screen for breaking up the Icoml bustible mixture as it enters the device.

Preferably the inlet and outlet openings of the combustion device are at opposite ends thereof, and, as shown in the particular -form illustrated, the spark plug and observation window openings are in the sides of the device andin line with each other.

Referring to the drawings vwhich illuswhich drawings form a part of this specifi-` cation, v

Figure 1 is a sectional view through the device;

Figure. 2 is a section substantially on the line 2 2 of Figure 1; n f Figure 3 is an elevation .of the device illustrated in Figure l; andlFigure 4 is a top view of the device. In these drawings the body 10 is hollow and isof substantially cylindrical form, being somewhat longer than its diameter. Its interior forms a combustion chamber 11 and at one end there is provision for an inlet and at the other end an outlet. As shown, the inlet 12 is formed in an elbow 13 which w is connected to a pipe 14 and is provided with an adjusting valve 15. The elbow 13 is connected to the body of the device by being threaded into a hollow nut 16, which nut is also threaded into the inlet end of the body of the device against a screen 17 which is provided for breaking up the particles of mixture into finer form.

At the outlet end of the body of the device there are lateral ears 18 by which the device may be secured to4 a support with screws 19, as shown. For properly positioning the body on the support, it is extended as in the form of a .boss 20, this boss entering an Opening 21 in the support 22.` lThis support 22 may be the Outer wall of 'a jacket surrounding the intake header of the motor, and in this case the interior of the combustion device will communicate with the in- 26, the points 27 of which extend well into the interior of the combustion device, and the boss 25 has an interior shouldei` 28 Vagainst which a'glassor other window 29 rests. A hollow nut 30 retains the observation `window in position.A By this arra ement of spark plug and window the 'con itions inside the combustion device maybe readily observed, both as to whether or not the .spark plug is firing and whether the correct mixture is being drawn into the combustion chamber.

It will be seen that the device provides an extremely compact arrangement of the various .functional elements of -a combustion heating means and it may be made and sold as a unit which reqires only that itsinlet and outlet be suita ly Connected with the motor and its spark plug connected with the ignition system.

The device is, of course, Capable of modiication in various ways without departing from the spirit of the invention.

Having thus described my invention,

Whatk I claim and desire to'secure by Letters said passage-for breaking up the mixture, 10 Patent is: said device also having a, lateral opening' 1. A combustion device having a'screened for a spark plug, a, spark plugin said latinlet opening atene end, an outlet opening, eral opening land extending into thefdeviee 5 and latex-e1 aligned openings for a. spark to a, point beneath said passage, en outlet v plug and window respectively. for said device, and an observation window. 15 2. A combustion, device having an inlet n testimony whereof. I aix my signaopening comprising a. downwardly extendture.

ing passage, means near the lower end of LIONEL M. WOOLSON.
